[PATCH] of: Turn of_match_node into a static inline when CONFIG_OF isn't set

From: Laurent Pinchart
Date: Tue Feb 11 2014 - 07:36:03 EST


when CONFIG_OF is disabled of_match_node is defined as a macro that
evaluates to NULL. This breaks compilation of drivers that dereference
the function's return value directly. Fix it by turning the macro into a
static inline function that returns NULL.
